We’re back at the California Science Center, final home of Endeavour, the shuttle that made 25 flights into space. Join the party as we celebrate the 53rd anniversary of humanity’s transition to spacefaring species with Yuri’s Night Executive Director Loretta Hidalgo Whitesides, Virgin Galactic CEO and Yuri’s Night co-founder George Whitesides, and astronaut Ron Garan, who heads Fragile Oasis. You’ll also get a Curiosity update from Emily Lakdawalla, and we’ll find out what happened this week in space history with Bruce Betts.
